Need help updating unsupported drivers

So I just now got Minecraft, and I'm setting it up when I'm notified that I need to update my drivers before I can proceed. The problem is that my Dell Studio 1555 (Pentium CPU, 4Gb RAM, and Intel graphics) is running Windows 8 which Intel doesn't support on my computer. I know it isn't a hardware issue because I have all the needed specs. Is there any other way to update my drivers to support newer versions of OpenGL? And if not, does anybody know if it would work on a Ubuntu partition?
